The Energy States of the Hydrogen Atom

• Bohr obtained an equation giving the energies of the stationary  states of the hydrogen atom:

• The energy of the ground state (n = 1) is:

• He defined zero energy (E = 0) as the state when the electron is  totally removed from the nucleus; in other words, when n = _.

• So E < 0 (i.e. negative) for any smaller n values.

• The energy difference between any two energy levels is given by:
